M2 Exchange

Heat exchange pump unit for hydraulic installations with insulation box, made of hot forged brass.

By the means of this heat exchanger it is possible to separate hydraulically the primary circuit fed by wood pellet boiler etc. from the secondary circuit (for example underfloor heating systems) in installations where it is not advisable to utilise the same fluid in both primary and secondary circuits.

Plate heat exchanger made of stainless steel AISI 316.  Prepared for the direct connection to the anti-condensing pump unit of the primary circuit and  to the mixed pump unit of the secondary circuit by means of the 1” male connections.  It is also possible to connect several fittings to the “T” connectors.

3 bar security unit with the pressure gauge 63mm (0-4 bar) and a draining valve are already provided in the “heating” circuit (secondary).

EPP insulation box measurements : 250 x 143 x 218mm

PN 10. constant temperature 120oC
Centre distance: 125mm
External connections: 1” male.
